Abstract:

Objective

To analyze the predictive value of serum periostin levels for early treatment responsiveness in children with cough variant asthma (CVA).

Methods

Fifty-nine children with CVA admitted to our hospital from June 2021 to November 2024 were enrolled. All children received inhaled corticosteroids combined with long-acting β2 agonists (ICS/LABA) for 28 days. Forty-eight children with good treatment responsiveness were assigned to the control group, and 11 children with poor treatment responsiveness were assigned to the observation group. Clinical data were compared between the two groups. Multivariate logistic regression was used to identify influencing factors, and receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of serum periostin levels for poor treatment responsiveness in CVA children.

Results

The observation group showed significantly higher values than the control group in: disease duration (2.48±0.41 months vs. 2.06±0.32 months), proportion with a history of recurrent respiratory infections 9 cases (81.82%) vs. 18 cases(37.50%), serum periostin levels (82.29±2.22 ng/ml vs. 78.33±4.42 ng/ml), and fractional exhaled nitric oxide (FeNO) (21.28±3.74 ppb vs. 18.33±1.80 ppb) (P<0.05). Multivariate logistic regression analysis revealed that serum periostin level (OR=1.346, 95%CI: 1.028~1.761) and FeNO(OR=1.670, 95%CI: 1.068~2.611) were independent risk factors for poor treatment responsiveness in CVA children (P<0.05). ROC curve analysis showed that the area under the curve (AUC) for predicting poor treatment responsiveness was 0.807 for serum periostin, 0.769 for FeNO, and 0.837 for the combination.

Conclusion

The level of serum periostin can predict the treatment responsiveness of children with CVA, which is of clinical significance.
